World Athletics President Sebastian Coe has warned any athletes tempted to use doping substances during the coronavirus pandemic, when drugs testing is proving more difficult, that they "will get caught".
"Clearly, because of lockdown, curfews and international travel restrictions, (drugs) testing has been more difficult," Coe, 63, told German broadcaster Deutsche Welle.
"But nobody should run away with the idea that there is no testing taking place at all. It is.
"I want to send a very clear message to the athletes: do not sit there thinking that this is a test-free zone. It isn't.
"If you choose to step outside the integrity of our sport, you will get caught."
